post	Released Cyclone Scheme 0.8.1	This release includes many performance enhancements and compiler optimizations.

Features

• Improved garbage collector performance for large heaps.
• Generate faster compiled code for:
  • car, cdr, and most built-in predicates.
  • Calls to list that contain less than five arguments.
  • Calls to map and for-each that only pass a single list.
• Allow optimization of some simple self-recursive functions.
• Allow the optimizer to beta expand a wider range of function calls.

Bug Fixes

• Fixed a bug where current-jiffy was returning total clock time of the process. Such an approach cannot be used to measure time accurately when more than one thread is executing concurrently.
• Prevent the possibility of an infinite loop by not beta expanding recursive function calls.
